Calculate the percentage composition of ...

Calculate the percentage composition of a solution obtained by mixing 300 g of a `20%` and 200 g of a `30%` solution by weight.

A

`50%`

B

`28%`

C

`64%`

D

`24%`

Text Solution

Verified by Experts

The correct Answer is:
D
Solute in 200 g of 30% solution =60 g
Solute in 300 g of 20% solution = 60 g
Total grams of solute = 120 g
Total grams of solution = 200 +300=500 g
% of solute in the final solution=`120/500xx100`=24%
